Will lucky Week 7 bring out a perfect set of predictions from the Big Ten bloggers? Both of us are still searching for perfection in this highly imperfect Big Ten season.

After a pair of identical 4-1 marks in Week 6, Adam Rittenberg maintains a four-game lead against Brian Bennett in the season standings. Those shrimp cocktails at St. Elmo's in Indianapolis -- on Brian's dime -- are sounding pretty good right now, but there's still a long way to go and time for Brian to catch up.

It's prediction time ...

IOWA at MICHIGAN STATE

Brian Bennett: Get ready for a classically rugged Big Ten game between two teams who love to pound the rock and play defense. Neither team will be able to sustain many long drives against strong defenses. But home-field advantage and a key turnover forced by the Spartans' defense will make the difference. Le'Veon Bell contributes two scores as he outduels Mark Weisman. ... Michigan State 17, Iowa 14

Adam Rittenberg: While I'm tempted to pick Iowa in the upset, Michigan State matches up well against the Hawkeyes on both sides of the ball. The Spartans' defense holds Weisman to 90 rushing yards and records a key second-half interception against James Vandenberg. Bell records 100 yards and two scores as Michigan State grabs the early lead and holds on for its second straight win. ... Michigan State 21, Iowa 17

NORTHWESTERN at MINNESOTA

Adam Rittenberg: Northwestern can't afford another poor start on offense, and I think the Wildcats come out of the gates a little stronger and take an early lead. Minnesota's Max Shortell makes some plays in the pass game, firing two touchdown passes, but Northwestern gets the ball in the hands of playmakers Venric Mark and Kain Colter a lot more often this week than last. Mark and Colter combine for three touchdowns and Northwestern survives a late scare to improve to 6-1. ... Northwestern 28, Minnesota 24

Brian Bennett: If the Gophers had a fully healthy MarQueis Gray, I'd be more likely to pick them here. As it stands, I don't think a gimpy Gray gives them enough firepower to get past Northwestern. Minnesota struggled against the run last time out against Iowa, and will do the same against Colter and Mark. A Jeff Budzien field goal provides the difference. ... Northwestern 31, Minnesota 28

WISCONSIN at PURDUE

Brian Bennett: It's practically do-or-die time for the Boilermakers, and I expect them to play as if their Leaders Division lives depend on this effort. In fact, they will lead most of the way after a couple of quick-strike scores early. But an improving Wisconsin offense chips away until Joel Stave hits Jared Abbrederis for a long touchdown in the fourth quarter, and the Badgers' defense hangs on late. ... Wisconsin 23, Purdue 20

Adam Rittenberg: You touched on the sense of urgency for Purdue and coach Danny Hope, and I think that'll be the difference in this game. A Boilers defense hungry to avenge last week's poor showing records an early takeaway against Stave. Both Caleb TerBush and Robert Marve play and fire touchdown passes. Although Wisconsin's Montee Ball records two rushing scores, the kicking game is the difference as Raheem Mostert breaks off a long return to set up the game-winning touchdown. ... Purdue 27, Wisconsin 24

ILLINOIS at No. 25 MICHIGAN

Adam Rittenberg: Little is going right for the Illini right now, and they catch Michigan at the wrong time. After a quiet first quarter, Wolverines quarterback Denard Robinson turns in another big performance (150 rushing yards, 175 pass yards, 2 rushing TDs, 2 passing TDs), and linebacker Jake Ryan records his first interception of the season. Versatile running back Josh Ferguson has a nice game for the Illini, but Michigan has far too much firepower and pulls away in the second quarter. ... Michigan 37, Illinois 14

Brian Bennett: The Illini's problems defending the spread and finding any kind of offensive rhythm don't bode well for this week's game in Ann Arbor. Robinson will throw for three touchdowns this week, and Michigan's defense holds Illinois to under 250 yards. ... Michigan 34, Illinois 10

No. 8 OHIO STATE at INDIANA

Brian Bennett: The Hoosiers are getting closer and closer to finally winning a Big Ten game. But it won't happen this week, as their shaky run defense is going to have a lot of trouble containing Braxton Miller and Carlos Hyde. Those two combine for four touchdowns, and Bradley Roby picks off another pass to stymie Indiana's mild second-half charge as the Buckeyes move to 7-0. ... Ohio State 42, Indiana 24

Adam Rittenberg: I've also been impressed with Indiana's ability to compete, but this is just a tough matchup against Big Bad Brax. Miller runs for 150 yards and two touchdowns, and Hyde records his second straight 100-yard rushing performance. Quarterbacks Cameron Coffman and Nate Sudfeld both play and have some success in the first half, and receiver Cody Latimer tests the Buckeyes' defense, but Ohio State shifts into fifth gear late in the second quarter and cruises to 7-0. ... Ohio State 45, Indiana 21
